3902 5580 d 5 h jermar /trunk/kernel/ Introduce a more platform-neutral name for programmed I/O.

The new API looks like pio_read_n() or pio_write_n(), where n is 8, 16 or 32.
The old API (i.e. inb(), inw(), inl(), outb() outw(), outl()) may have made
some people think that the interface is only to be used with the separate I/O
space. That's not the case. This API is to be implemented on all platforms
so that we can finally have really generic kernel device drivers.		  
3892 5580 d 23 h jermar /trunk/ Get rid of CONFIG_DEBUG_AS_WATCHPOINT.  
3891 5581 d 0 h jermar /trunk/ Get rid of CONFIG_SIMICS_FIX.  
3890 5581 d 0 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3880 5583 d 0 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup		  
3802 5607 d 5 h decky /trunk/kernel/arch/ fallback to VGA registers if VESA routine fails  
3790 5618 d 8 h svoboda /trunk/kernel/ Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.  
3788 5618 d 22 h svoboda /trunk/kernel/ Unify newlines in fault_if_from_uspace() format strings. (Remove them and print newline automatically). Also start messages with caps.  
3779 5622 d 6 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3751 5630 d 9 h svoboda /trunk/kernel/arch/ia32/src/drivers/ Revive kernel EGA fb driver. Plus fix bug -- was using memcpy() for scrolling instead of memmove().  
3709 5641 d 1 h decky /trunk/kernel/ invert VGA 3:2:3 palette to reflect changes in revision 3692  
3707 5641 d 1 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)		  
3672 5652 d 0 h jermar /trunk/ Merge sparc branch to trunk.  
3631 5662 d 23 h jermar /trunk/kernel/arch/ia32/src/ The IA-32 manual is very secretive about the fact that the SYSENTER instruction
disables interrupts (I found only one evidence of this in the instruction's
pseudo code). The sysenter_handler needs to reenable the interrupts in order to
preserve the preemptive nature of the kernel.		  
3485 5712 d 23 h jermar /trunk/ Support for SYSENTER on ia32.  
3274 5769 d 5 h jermar /trunk/ memcpy(), memmove() and similar functions return dst instead of src.
Fix all implementations, including those in assembly. ppc32 assembly
version didn't seem to be affected by this.		  
3240 5779 d 10 h decky / move unfinished ObjC support to a separate branch  
3234 5783 d 5 h decky /trunk/ reintroduce support for MSIM text console in user space  
3227 5784 d 1 h decky /trunk/kernel/arch/ia32/src/drivers/ remove unnecessary newline  
3222 5802 d 4 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)
